Why you can`t use the 3asy UDID bypass guide with the iPhone OS 4.0 Beta2

Apple announced the iPhone OS 4.0 beta2 today.


I tried working on the redsn0w 0.9.5 beta2 to make it able to jailbreak the new OS 4.0 beta2.
The jailbreak on the beta1 is done by using an already known exploit. As apple released the 3.0.1 update of the 3.0 software you were able to use the redsn0w release for the 3.0 firmware to jailbreak 3.0.1.

The idea was, in case that the modifications weren`t big, to simply edit the redsn0w 0.9.5 beta2 by changing the names of the .dmgs (like the 018-7262-033.dmg to 018-7411-002.dmg ), -k and -iv keys (posted by iH8snow here) and the sha1 checksum (from "a855ef177392d3df6aa28bc3557d6a87a57846ae" for the beta1 to "865e331b9588ce20b949cbf11ca2e9a4ee439fca" for the beta2).
The last part with the sha1 checksum will let redsn0w recognize the new beta2 and display ".ipsw successfully identified".

This is how far you get, by clicking on "next" Redsn0w crashes in the Kernel Part and can not work with the Beta2.



This happens because Redsn0w is not able to patch all the files even if it can decrypt the firmware with the keys you manually entered.


We have to wait for the 0.9.5 beta3 if there will be one! As soon as I get any news about the 4.0 beta2 I`ll post them here, so stay tuned.
